Background
The loading and unloading bridge of the conveyor is mainly used for loading and unloading heavy equipment and equipment with poor passing performance or material air transportation. At present, due to the development of the air transportation industry, various transportation machines and various loading and unloading equipment, airports often face different shutdown heights of the airplanes and the transfer demands of multiple machines, the writing equipment is provided with lifting devices, crawler belt transmission type devices can have different transmission angles, the usable space of the airports is strictly limited, and the loading and unloading bridges are required to be carried randomly.
The cargo bridge that current large-scale cargo airplane carried at random is relatively simple and crude, is usually directly connected with aircraft afterbody hatch door sloping platform, and the goods that need load and unload are various, like vehicle etc. itself has the throughput ability, and the best route is practical inclined plane cargo bridge, utilizes self throughput ability to get into the aircraft cargo hold, but the often suggestion cargo bridge that the aircraft carried by oneself, it is great to form the slope with the cooperation of aircraft sloping platform, and the goods reaches the juncture of cargo hold and sloping platform and easily touches the bottom, and the less cargo bridge volume of longer slope is great, can not carry at random.
There is also a cargo bridge for loading and unloading a self-contained conveyor, for example, chinese patent document CN 109051895A describes an auxiliary cargo bridge for self-contained up and down conveyors, which comprises legs, bridge joints, ramp modules, springboards and hook assemblies. The bridge joints are divided into two rows and are arranged side by side, each row of bridge joints are sequentially and longitudinally connected, and the two bridge joints arranged side by side are transversely connected through a connecting rod, so that a double track channel is formed. A ramp module is arranged above the double-track channel, one end of the gangboard is connected with the double-track channel, and the other end of the gangboard is put on a ramp of the conveyor. The hitch assembly is used to connect the double track aisle and the conveyor ramp, thereby self-arming the transport cargo hold from the ground through the ramp module, bridge and gangway. The goods bridge is equipped by oneself to this kind, forms the goods bridge of certain slope through the cooperation of bridge festival and ramp module, and the slope of goods bridge is decided by the ramp module completely, often needs the goods bridge of different slopes to the equipment by oneself of different throughput in reality, needs different ramp module just can satisfy, and the ramp module can not fold, inconvenient random carrying.
